We reset back to before everything turns to shit, but as we’ve learned from the previous arcs, there’s plenty of shit lurking just beneath the shiny happy surface of Keiichi & Co.’s daily life in Hinamizawa. Having had Rika and Mion/Shion-centric arcs, now it’s time for the focus on Satoko.
When Mion brings in fancy leftovers, Mion and Keiichi agree to a cooking duel, but Keiichi is abysmally bad at cooking. Seriously, he’s so clueless he almost burns his house down. Luckily Satoko and Rika are there to not only put out the fire, but salvage his dinner, and Kei-chan is thankful for both.
As Rika puts it to Kei before biking home for the night, Satoko is in need of someone Rika can’t replace: her big brother Satoshi, who ran away from home under myterious circumstances. Despite, or perhaps because of their sibling-like combative manner with each other, Kei makes for the perfect surrogate nii-nii.
Simple things like shopping for ingredients, cooking them, and sharing meals together clearly brightens Satoko’s day immeasurably. Similarly, when Satoko needs someone to cheer her on in a crucial at-bat, Kei arrives just in time, and as a result, she hits the winning home run and wins her team free BBQ.
At this BBQ, during which everyone has fun, Kei meets someone new: Irie, who loves Satoko’s smile, and while he can’t adopt her for “various legal reasons”, has no qualms about citing his plans to eventually ask for Satoko’s hand in marriage when she comes of age. Shion is similarly enamored of Satoko, considering herself a big-sis figure.
Irie’s words to Kei—never make Satoko cry—sound like his prime directive for this arc, which he’ll have to follow to avoid disaster. But that will surely come anyway, since Kei overhears two boys talking about how Satoko’s brother Satoshi was a victim of Oyashiro’s curse.
The destructively-curious Kei is eager to pick at this particular scab, and while Rena will have none of it, Mion tells him more: Satoko’s parents were the leaders of the pro-dam movement, as the gov’t offered big payouts to anyone who agreed to move out of the village. They died falling off an observation deck, which is super-suspicious, while Satoshi is believed to have run away to avoid the curse, but could also have been “demoned away”.
In any case, part of “not letting Satoko cry” means keeping all this under wraps, especially around her. And as we learn, and as I’ve suspected since that unsettling end credits image of her looking frightened as a man in a Hawaiian shirt looms over her, Satoko already has enough to cry about.
As we see the loud, drunk, boorish “Uncle Teppei” lead her into an isolated house, It’s almost a certainty some kind of physical and/or sexual abuse is taking place. For all the people who love Satoko and are watching over her, there’s clearly a huge gap in their blanket of protection. However explicit the arc gets about this, I hope Kei & Co. can manage a way to free Satoko from this particular hell…assuming they ever learn about it.
